PlanTEA-WM: A Multi-User Web Platform for Routine Planning and Anticipating Everyday Situations in Individuals With Autism Spectrum Disorder

Abstract

PlanTEA-WebMultiuser (PlanTEA-WM) is an innovative web platform designed to enhance planning, anticipating and exposing anxiogenic situations for individuals with Autism Spectrum Disorder (ASD). Conceived as an evolution of the PlanTEA mobile application, this multi-user solution facilitates the creation of visual routines through pictograms, integrating Large Language Models (LLMs) to automate and simplify the routine-generation process. PlanTEA-WM offers essential functionalities such as a shared calendar, an invitation system for collaboration among families, educators, and therapists, and plan exportation in versatile formats like XML and PDF. To improve accessibility and collaborative use, PlanTEA-WM stores user data in a remote database, supporting multi-user access from multiple devices. The platform has been preliminarily evaluated in collaboration with specialized autism associations, with results indicating high usability, accessibility, and overall acceptance. These findings highlight its potential to foster autonomy in individuals with ASD and strengthen coordination within their support environments. Within this scope, the contribution lies in combining multi-user management, LLM-assisted routine generation, and standards-based export in a single web platform designed around ASD-oriented guidelines and workflows.
